Rosaceae, the rose family, is a medium-sized family of flowering plants, including 4,828 known species in 91 genera.
Crataegus, commonly called hawthorn, quickthorn, thornapple, May-tree, whitethorn, or hawberry, is a genus of several hundred species of shrubs and trees in the family Rosaceae, native to temperate regions of the Northern Hemisphere in Europe, Asia, North Africa, and North America. The name "hawthorn" was originally applied to the species native to northern Europe, especially the common hawthorn C. monogyna, and the unmodified name is often so used in Britain and Ireland. The name is now also applied to the entire genus and to the related Asian genus Rhaphiolepis.
In botanical nomenclature, a form is one of the "secondary" taxonomic ranks, below that of variety, which in turn is below that of species; it is an infraspecific taxon. If more than three ranks are listed in describing a taxon, the "classification" is being specified, but only three parts make up the "name" of the taxon: a genus name, a specific epithet, and an infraspecific epithet.
Crataegus monogyna, known as common hawthorn, one-seed hawthorn, or single-seeded hawthorn, is a species of flowering plant in the rose family Rosaceae. It is native to Europe, northwestern Africa, and West Asia, but has been introduced in many other parts of the world.
A botanical name is a formal scientific name conforming to the International Code of Nomenclature for algae, fungi, and plants (ICN) and, if it concerns a plant cultigen, the additional cultivar or Group epithets must conform to the International Code of Nomenclature for Cultivated Plants (ICNCP). The code of nomenclature covers "all organisms traditionally treated as algae, fungi, or plants, whether fossil or non-fossil, including blue-green algae (Cyanobacteria), chytrids, oomycetes, slime moulds and photosynthetic protists with their taxonomically related non-photosynthetic groups ."
In horticulture, a graft-chimaera may arise in grafting at the point of contact between rootstock and scion and will have properties intermediate between those of its "parents". A graft-chimaera is not a true hybrid but a mixture of cells, each with the genotype of one of its "parents": it is a chimaera. Hence, the once widely used term "graft-hybrid" is not descriptive; it is now frowned upon.
Crataegus laevigata, known as the Midland hawthorn, English hawthorn, woodland hawthorn, or mayflower, is a species of hawthorn native to western and central Europe, from Great Britain and Spain east to the Czech Republic and Hungary. It is also present in North Africa. The species name is sometimes spelt C. levigata, but the original orthography is C. lævigata.
Göygöl National Park — is a national park of Azerbaijan. It was established in an area in Goygol Rayon administrative district on April 1, 2008 on the basis of the former "Goy Gol State Reserve" that was established in 1925 and which it superseded, on a surface area of 12,755 hectares (127.55 km2). It was enlarged from 6,739 hectares (67.39 km2) of the former state reserve to its current surface area as a national park.
Crataegus douglasii is a North American species of hawthorn known by the common names black hawthorn and Douglas' thornapple. It is named after David Douglas, who collected seed from the plant during his botanical explorations.
The name Crataegus oxyacantha L. has been rejected as being of uncertain application, but is sometimes still used.
Crataegus azarolus is a species of hawthorn known by the common names azarole, azerole, and Mediterranean medlar. It is native to the Mediterranean Basin and is a common plant there, growing on sites comparable to those the European common hawthorn grows on. In the Arab countries it is the most common hawthorn species. When growing in the wild, the azerole bears plentiful crops of haw fruits, which are similar to the haws of the European common hawthorn, but more plump.
Crataegus coccinioides is a species of hawthorn known by the common names Kansas hawthorn and large-flowered cockspurthorn. Crataegus coccinioides is native from Kansas, to New England, and the southernmost parts of Ontario and Quebec. It has large flowers and leaves and fruit that appear pinkish until polished to reveal the red colour underneath the wax bloom. Crataegus coccinioides is a synonym of Crataegus dilatata.
Crataegus intricata is a species of hawthorn known by the common names Copenhagen hawthorn, Lange's thorn and thicket hawthorn. It is native to eastern Canada and the eastern United States. Its fruit are brown to red.
Crataegus punctata is a species of hawthorn known by the common names dotted hawthorn or white haw that is native to most of the eastern United States and eastern Canada. While some sources claim it is the state flower of Missouri, the actual legislation does not identify an exact species. Furthermore, the Missouri Department of Conservation asserts the Crataegus mollis was specifically designated as the state flower.
Crataegus succulenta is a species of hawthorn known by the common names fleshy hawthorn, succulent hawthorn, and round-fruited cockspurthorn. It is "the most wide-ranging hawthorn in North America", native to much of southern Canada, and the United States as far south as Arizona, New Mexico, Kansas, Missouri, North Carolina, and Tennessee. In this wide area there are many variant forms that have received species names, but can also be considered as synonyms. It is thought to be the parent, along with Crataegus crus-galli, of the tetraploid species Crataegus persimilis.
Stigmella oxyacanthella is a moth of the family Nepticulidae. It is found from Fennoscandia to the Pyrenees, Italy and Bulgaria, and from Ireland to central Russia.
Stigmella crataegella is a moth of the family Nepticulidae. It is found from Fennoscandia to the Iberian Peninsula, Italy and Macedonia, and from Ireland to Poland and Romania.
Crataegus laciniata is a species of hawthorn found in Morocco, Algeria, Spain and Sicily.
Fritillaria pontica, the Pontic fritillary, is a species of flowering plant in the genus Fritillaria native to the mountains of the Balkans, the Aegean Islands and Anatolia. Shade tolerant and easy to grow, it has gained the Royal Horticultural Society's Award of Garden Merit.
